PN ATI Capstone Proctored Comprehensive Assessment B Quizlet

Correct Answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

Correct Answer: D

Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.

Correct Answer: B

Rationale: Rheumatoid factor is a specific marker for rheumatoid arthritis. It is often elevated in clients with this autoimmune condition, helping to confirm the diagnosis. Erythrocyte sedimentation rate (ESR) and antinuclear antibody tests can be supportive but are not specific for rheumatoid arthritis. Serum calcium levels are not typically used to confirm this diagnosis.

Correct Answer: D

Rationale: The correct action for the nurse to take when inserting an indwelling urinary catheter into a female client is to inflate the catheter balloon after urine begins to flow. Inflating the balloon before urine starts flowing can lead to incorrect placement in the urethra, causing trauma. Cleansing the labia and meatus should be done before the insertion, but the crucial step of inflating the balloon should occur after the catheter is correctly placed. Asking the client to bear down is not necessary during catheter insertion.

Correct Answer: C

Rationale: The correct action for the nurse to take before performing a closed intermittent bladder irrigation is to apply sterile gloves. Sterile gloves help maintain asepsis, reduce the risk of infection, and ensure patient safety during the procedure. Aspirating the irrigation solution from the bladder (Choice A) is not a standard step in closed intermittent bladder irrigation. Inserting the tip of the irrigation syringe into the catheter opening (Choice B) can introduce contaminants into the system. Opening the flow clamp to the irrigating fluid infusion tubing (Choice D) should only be done after ensuring all equipment is ready and the nurse is gloved to maintain sterility.
